2005 Chevrolet Colorado Repair Question
2005 Chevy Colorado P0506 code - Idle air control lower tha
2005 Chevy Colorado Four Wheel Drive Automatic 60.000 miles
My check engine light came on with a P0506 code - Idle air control system rpm lower than expected. Several of the option that I found on the web suggest that it could be the PCV valve or the Idle air control Valve (IAC). Can anyone tell me were these are located on a 2005 5 cyl colorado. I did find a site that tells how to test the IAC valve/motor, but I want to make sure I have the correct devices. Thanks

On rare occasions, a SES light may be experienced due to DTCs P0105, P0106, and/or P0506. There may or may not be an idle complaint accompanying the SES light. This may be due to excessive carbon build up in the throttle body.

I had this code pop up at 55K on my 2005 Mustang GT.
What I did to clear this code was clean my TB.
I turned the key to the "on" position (engine not running) and placed weights on my accelerator peddle. This opened the butterfly on my TB. From there I just used carb cleaner and a clean rag to clean the TB. Doesn't have to be a whole lot of gunk to make this code appear.
